re: What would Usain Bolt's 40 yard dash time be?

So when Bolt ran 9.58 his splits went like this
1.85
1.02
.91
.87 * .65 == .5655
Add these together, you get:
4.3455
And this is fair to compare to a 40 yd dash time at the combine in that Bolt's .165 reaction time is taken out of the calculation (at the combine the timing starts when they move, in an olympic race the time starts off the gun, so you exclude the reaction time to get an equivalent measure).
EDIT: as a rough way to account for the fact that he was still accelerating at 36.5 meters, we can half his 30-40 split and his 40-50 split, and use that as his 30-40 split. This gives us .559 for the last 6.5 meters. This takes it down to a:
4.339
